Microwave Plasma Sintering of Alumina

Abstract

A tunable single mode (TM012) microwave cavity was designed to initiate and sustain a plasma for sintering ceramic materials. Almost 100% of the incoming microwave energy could be coupled to the plasma under optimal tuning conditions. An optical fiber thermometer was used to continuously monitor the temperature of alumina specimens during plasma sintering. The sintering temperature and resulting density of the specimens were dependent on gas content at constant net power absorption.
